The server's host key does not match the one PuTTY has
cached in the registry. This means that either the
server administrator has changed the host key, or you
have actually connected to another computer pretending
to be the server.
The new rsa2 key fingerprint is:
ssh-rsa 2048 time :2c:d8:21:3e:ff:bb:d6:65:d0:e6:time :4d:c5
If you were expecting this change and trust the new key,
hit Yes to update PuTTY's cache and continue connecting.
If you want to carry on connecting but without updating
the cache, hit No.
If you want to abandon the connection completely, hit
Cancel. Hitting Cancel is the ONLY guaranteed safe
choice.
